Claims
- 1. A solar heat collector comprising:
- an evacuated double-tubing type solar heat collector pipe having a cylindrical inner pipe and a cylindrical outer pipe;
- a header pipe including a continuous outer surface having a supporting portion for a heat pipe being disposed on said outer surface thereof;
- a heat pipe formed of a heat-conductive material having a first end portion connected in surface contact with said supporting portion of said header pipe and a second end portion operatively positioned concentrically within the inner pipe of said solar heat collection pipe;
- at least two ribs connected at inner ends with the outer wall of said heat pipe and extending symmetrically radially outwardly from said heat pipe toward said inner pipe of said solar heat collector pipe;
- at least two arcuate heat-conductive plates separate and circumferentially spaced apart from each other and in surface contact with said inner surface of the inner pipe of said solar heat collector pipe, each of said plates being connected with the outer end of the corresponding one of said ribs;
- said heat pipe, said ribs and said plates being formed of the same material and as one integral piece; and
- a thermal insulating material enclosing said header pipe and the first end portion of said heat pipe connected with the header pipe;
- said supporting portion of said header pipe being recessed in a form coresponding to said heat pipe for receiving said heat pipe therein.
- 2. A solar heat collector according to claim 1 having means for detachably securing said heat pipe to said supporting portion of said header pipe including U-shaped members fitted over said header pipe, and a keeper pipe fixed to said members.
- 3. A solar heat collector according to claim 1, wherein said heat pipe is circular in cross section and includes four ribs projecting radially outwardly therefrom and four heat-conductive plates each being formed integrally on end portions of each of said four ribs.
- 4. A solar heat collector according to claim 1, wherein said heat pipe is circular in cross section and includes two ribs projecting radially outwardly therefrom and two heat-conductive plates each being formed integrally on end portions of each of said two ribs.
- 5. A solar heat collector according to claim 1, wherein said heat pipe is rectangularly shaped in cross section and includes four ribs projecting outwardly from corner portions of said rectangle and four heat-conductive plates each being formed integrally on end portions of each of said four ribs.
- 6. A solar heat collector according to claim 1, wherein said heat pipe is rectangularly shaped in cross section and includes two ribs projecting outwardly from short sides of said rectangle and two heat-conductive plates each being formed integrally on end portions of each of said two ribs.
